Choose by problem, not by format
- Need fewer files? Start with Merge PDF.
- Wrong page order or orientation? Organise PDF is the cleaner route.
- Can’t search a scan? That’s an OCR problem, not a PDF-to-text problem.
Merge, split, organise, compress, convert and edit PDFs without forcing every document job into one oversized editor.
PDF Tools
Choose the operation that matches the file problem in front of you. Page-level jobs, conversions, OCR and document cleanup behave differently, so each tool keeps its own controls and limits visible.

PDF tools for the jobs people actually run into
PDF work gets messy for a simple reason: a PDF can be a clean digital document, a stack of scanned images, a form, a presentation exported sideways, or all of those things in one file. One button can't solve every version of that problem.
Kaazo separates those jobs. Merge files when order is the issue. Organise pages when the document is right but the sequence isn't. Use OCR only when the page is an image and searchable text is missing. Redact when information must be removed—not merely covered. That distinction matters.
Most supported PDF operations run in your browser. The trade-off is device memory and format complexity. A 300-page scan with embedded images will ask far more of a browser than a six-page text PDF.
Keep the source
- Cropping isn’t secure redaction.
- A visible signature isn’t the same as a certificate-backed digital signature.
- Complex forms, layers and fonts deserve a quick export check.
